Q & A

What did Amelia Earhart say about the decision to act?

Amelia Earhart stated, 'the most difficult thing is the decision to act; the rest is merely tenacity,' emphasizing the importance of taking action.

What is space junk, and why is it a concern?

Space junk refers to man-made objects in space that are no longer in use, including defunct satellites and tiny debris. It poses a threat to both manned and unmanned spacecraft due to the high speeds at which it travels.

How is fossil fuel emissions in space impacting the environment?

Fossil fuel emissions from for-profit companies competing in space exploration are changing the atmosphere in measurable ways, potentially harming the ozone layer and Earth's climate.

What is the goal of the Italian firm Deorbit?

Deorbit aims to decrease the risk of overcrowding in space by using a specially designed vehicle for relocating, cleaning up, and repairing satellites in geostationary orbit.

What does the GE vehicle developed by Deorbit do?

The GE vehicle can dock with non-functional satellites to extend their life, relocate them, send defunct satellites to higher orbits, or guide them to burn up upon re-entry into the atmosphere.

Which state in the U.S. experienced the largest recorded earthquake?

Alaska holds the record for the largest earthquake in U.S. history, with a magnitude of 9.2 that struck Prince William Sound on March 28, 1964.

What recent seismic activity has occurred in California?

California has experienced multiple earthquakes recently, including a 4.4 magnitude quake in Pasadena and a 4.7 magnitude event near Malibu, raising concerns about potential larger earthquakes.

What is the San Andreas fault known for?

The San Andreas fault is California's largest and most famous fault, where the Earth's tectonic plates push against one another, leading to significant seismic activity.

How do scientists prepare for potential earthquakes in Los Angeles?

Scientists do not predict earthquakes but assess probabilities over a 30-year window to help design buildings and infrastructure that can withstand future seismic events.

What unique product did the Japanese toy maker Mega House recently unveil?

Mega House unveiled the world's smallest Rubik's Cube, measuring just 5 mm on each side and requiring tweezers to solve due to its delicate components.
